I think that i have my new ar sighted in ok 25yrd. what i have a question is that if i am dead on at 25yrd (which I am ),i will be good again at 300...Correct? Now my local range only goes to 100yrds. How high should I be at 100. I am very novice and these are the things I have questions about. I think that my poi is 5 inches high give or take from my poa...plus I gotta factor that it was my first time out. So i guess i am asking what should I expect the difference should be?
